Screen Capture with Desktop computer software

A screencast is a digital recording of computer screen output, also known as a video screen capture, often containing audio narration. The term screencast compares with the related term screenshot; whereas screenshot is a picture of a computer screen, a screencast is essentially a movie of the changes over time that a user sees on a computer screen, enhanced with audio narration.

Screencasts can help demonstrate and teach the use of software features. Creating a screencast helps software developers show off their work. Screencasts are a useful tool for ordinary software users as well, to help report bugs (the movie takes the place of potentially unclear written explanations) or to show others how a given task is accomplished in a specific software environment. Screencasts are excellent tools for learning how to use computers, and several podcasts have started to teach computer users how to use software through screencasts.

Video NLE Software

video nleNon-linear editing for films and televisionpost-production is a modern video editing method which enables direct access to any video frame in a digital video clip, without needing to play or scrub/shuttle through adjacent footage to reach it, as was necessary with historical video tape linear video editing systems. It is the most natural approach when all assets are available as files on hard disks rather than recordings on reels or tapes, while linear editing is related to the need to sequentially view a film or read a tape to edit it. On the other hand, the NLE method is similar in concept to the "cut and paste" technique used in film editing. However, with the appropriation of non-linear editing systems, the destructive act of cutting of film negatives is eliminated. Non-linear, non-destructive editing methods began to appear with the introduction of digital video technology. It can also be viewed as the audio/video equivalent of word processing, which is why it is called desktop video editing in the consumer space.
